Thanks for the help Dragon, much appreciated. Don't get me wrong, there's absolutely nothing wrong with your training pack, on the contrary! It is excellent and that's why I'm looking at it when making my own.
I just want to learn how to do mission building and making a training mission for me and my mates seemed like a good start, that's all. I've been flying your training missions quite alot, trust me. :)
Quite annoying that you can't give ground units patrol patterns without making a gazillion waypoints to prevent them from running out during the mission. The mission editor is quite good but I find that it's missing a few important and basic features.
Thanks again for your help, cheers!
